<h1>Fixed positioning</h1>

<p>
    I am a basic block level element. My adjacent block level elements sit on new
    lines below me.
</p>

<p class="positioned">I'm not positioned any more...</p>

<p>
    We are separated by our margins. Because of margin collapsing, we are
    separated by the width of one of our margins, not both.
</p>

<p>
    inline elements <span>like this one</span> and <span>this one</span> sit on
    the same line as one another, and adjacent text nodes, if there is space on
    the same line. Overflowing inline elements
    <span>wrap onto a new line if possible — like this one containing text</span>,
    or just go on to a new line if not, much like this image will do:
    <img src="long.jpg" />
</p>
